I'm not saying you shouldn't breed them. I'm saying if you do, you shouldn't label them as a guess. Let the buyer know that there is no paper work, that they could be crossed, etc.
I think it becomes a problem when people dont pass this info along.
Say a kid goes to show and picks up a BCI labeled as a Red Tail Boa. 5 years from now he gets into breeding without doing a ton of reserch. He picks up a BCC thinking he wants to breed Red Tails. Crosses it with the BCI, say the litter comes out looking more like true BCCs. Now he has his own booth selling a cross as a true form. Then the cycle starts all over.
If no one keeps the bloodlines pure, then we might lose them forever one day.
Remember I said I have a couple of pairs going now. I don't have full history or papers. I will not be selling them as a pure line of anything. It would be a guess at best.
I think the bigger breeders of locality Boas have paper work going back to were the snake was caught in the wild.
There are the purest out there.
